RADIATOR.

Application filed November 30, 1926, Serial No. 427,300. Renewed August 5, 1926.

My invention relates to heat dissipating devices and it has particular relation to apparatus of the character designated that is adapted for use with electrical or other apparatuswhich is normally enclosed witlv in a tank and immersed in a cooling fluid.

The object of my invention is to provide a new type of radiator unit in which each individual unit, while spaced from the next adjacent unit, will serve to prevent distortion thereof that may he caused by abnormal pressure of the fluid contained therein.

More specifically. my invention relates to the particular construction of the individual units, which, when arranged. in side-by-side relation constitute a radiator section.

Heretoforo, it hashcen customary to construct radiators by fastening a plurality of pipes disposed in spaced side-hy-side relation between two common end connections or headers. These pipes, being constructed of relatively heavy material, do not require any support therehetween. In my copending application, Serial No. 427,189, filed of even date herewith, I have disclosed aradi ator comprising a plurality of envelope-like structures disposed in side-by-side relation. My present invention is a, modification of a structure disclosed in my copending application, and provides a means for rein 0 ing each of the units of a-radiator section from the next adjacent unit.

According to my invention, each unit is provided with extruded portions which engage similar extruded portions 01 the next ad acent units." Thus each unit prevents distortion of one side of the next adjacent unit. Also, if desired the units may be provided with indented portions, the inner sur-. faces of which are attached together. These indented portions may be of such form as" to direct the flow of the cooling liquid" throughout said units.

In the accompanying drawings, Figure 1 is a perspective view of one of two similar pressed metal members which, united, constitute a unit of a. radiator embodying my invention 4 Fig. 2 is a view similar to that shown in Fig. 1, of another form of radiator constructed in accordance with my invention.

Fig. 6 is a cross-sectional view of the structure shown in Fig. 5 taken'along the line VI-VI thereof. For a more detailed understandin of m invention, reference mey nowv be had to Figs. 1, 3 and 4, in which a tank, not shown, is provided with a radiator 8 com prising a plurality of individual units 9. The radiator section 8 is attached to the" tank by means of connecting pipes 16. Each of the units 9 is composed o two similarly presseld metal members 11, as host shown in 1g. of a rectangular member of substantially dish-shape having offset portions 12 at each end thereof. A flange 13 extends around the entire outer edge of each of the members .11. The flanges 13 of the twoco-oppr-i us sting sections are welded together, t forming a metallic envelope or unit '9". The central portion ofthe outer surface of eachmember 11 is provided with aplu- Each of the members 11 consists rality of spaced extrusions 14. The extrw sions 14 are integral. with the main body portion of the member 11, being merely pressed outwardly into an adjacent parallel plane. When the units are assembled, these extrusions engage similar extrusions upon the adjacent unit, thereby causing each unit to be reinforced. The extrusions of adjacent units may,if desired, be welded together at their point of oontah- 1 Allof. the intermediately dis enses may be su portedin. this manne -but the; 1
